kitten - that's a ridiculous argument. there were only two sides! people had lots of different reasons for voting the way they did. they voted for the policies, not their fellow voters.
(for the record, I am a remainer who is trying to put a positive face on what has happened - but i know a lot of people who voted leave based entirely on their fears for Europe's economic stability [and one who feels passionately that the EU has royally fucked over a lot of people in Greece, spain and southern Italy].
one of my friends is a Tunisian investment banker and he says if he could have voted, he would have voted out like a shot, because he thinks there are far better financial prospects outside the EU. i don't agree with him, but now i hope he's right!
